I have been experiencing pain in my right hand for about a few months.The pain started in my wrist and affects both the palm and the back of my hand.When I move my fingers, I feel sharp, pinching, and tingling sensations, especially nerve pain in my index finger.Sometimes, the pain and tingling radiate from my hand up my forearm to my shoulder, neck, and upper back.I also experience heaviness and tightness in my forearm and shoulder.The pain worsens with movement, hand use, and prolonged phone use, and slightly improves with rest.I do not have constant numbness, but I feel nerve-related pain, particularly in the index finger.
